This chapter addresses the conduct of NATO hostilities against the FRY, and international attempts at settlement. It is argued that the scale and swiftness of the FRY/Serbian campaign of ethnic persecution in Kosovo bolstered NATO cohesion. Furthermore, when the ICTY indicted the top leadership of the FRY/Serbia, Belgrade was stripped of its legitimacy, with important implications for international perceptions of NATO's use of force. From the end of March 1999, serious efforts were made to settle the conflict. A set of agreed principles on a political solution was adopted by the G-8 on 6 May 1999. This was accepted by FRY/Serbia on 9 May, and emerged as Security Council Resolution 1244 (1999) on 10 June, providing for complete withdrawal of Serbian forces from Kosovo and the placing of the latter under exclusive UN control. In addition, a Military Technical Agreement addressed immediate issues of military withdrawal.
